To all wlw/mit may concern.'

Be it known that we, FRANK Hnnnnv FvANs, a subject of the King `of GreatBritain and Ireland, and residing at Wilton (lottage, Beaconsfield, inthe county of Buckingham, En land, and HAROLD AGUTTER EVANS, a su jectof the King of Great Britain and Ireland, and residing at 26 MaybankAvenue, South I-Iarrow, in the' county of Middlesex, England, have madea certain new and useful Invention in Fmibossing A paratus, of which thefollowing is a speci cation.

'Ihis invention relates to embossing machines of the kind known ascutter crush machines such as are used for embossing let ters, numeralsor designs on cardboard or the like, and at the same time cutting outand punching colored paper or the like into recesses in the cards formedby the dies which latter are necessarily formed with cutting edges. Inthis way, by using cards of one color and pieces of paper or the like,or one or more card colors, together with suitable dies, the machine canemboss words, letters, figures and designs in any desired color schemeon cards or the like, at one opera.- tion. 'Ihese machines, whileadapted for many dihierent purposes, find particular application in themaking of show cards, price tickets and the like, for use in shops,places of business and exhibitions.

rIhe object of the invention is to provide a cutter crush machine whichis simple of construction, efficient in operation and economical ofmanufacture.

A further object of the invention is to provide a machine of thischaracter which affords many advantages over machines of other structuredesigned for the saine or substantially the same purpose.

'further objects of the invention will appear more fully hereinafter.

rI`he invention consists in the construction, combination, location andrelative arrangement of parts, all as will be more fully hereinafter setforth, as shown in the accompanying drawing and finally pointed out inthe appended claims.

Referring to the drawing:

Figure 1 is a longitudinal sectional elevation.

Fig. 2 is a transverse sectional elevation. Fig. B is a plan view.

In order to give satisfactory results a a; a chine to be used for thepurpose of t invention must be simple in construction and operation, andwhich should require but' one operator. It should be so veel that'thenecessary pressure is in all cases applied with certainty and withoutdue effort: We have found that diderent spes and sizes of dies arerequired to be impressed into the cards and that ifl the impressiondepthis insucient the resulting edect is unsatisfactory, while too greata rere will not only frequently spoil the e ect but also cause the diesto wear out very rapidly. Finally, the machine must be so arranged thatthe pressure is evenly dissipated no matter what the osition of the diesmay he.

It is among t e special purposes vof our present invention to provide amachine which answers all of these requirements.

In accordance with our invention, we supply a machine consistinggenerally of al lower platen mounted on a table pivoted to the frame ofa machine, an upper platen in fixed but adjustable relationship to theframe, and a cam shaft mounted in bearings in the frame and adapted tolift the table so that the work may be pressed between the two platensso adjusted that the maximum lift of the lower platen is parallel withthe upper platen. We also provide means for adjusting the upper platento any relationship relative to the frame to suit the thickness of thework or the desired depth of impression. Furthermore, we provide meanswhereby the dies may be readily changed and the parts requiring cleaningeasily gotten to.

Referring to the drawings t atea the table which is pivoted to the bedpte a, asA shown, a convenient distance remote from the center of thepressure application, as will be more fully hereinafter set forth. Thelower platen c rests on the table and ia movable backwards and forwardsso as to facilitate the setting of the work. For t purpose a light metalframe d' which can be easily handled, is fastened to the platen andextends therefrom along the direction of sliding relative to the table.Any table stop may be employed to detee the position of the platen forthe application of pressure. ardened steel p platea e nus, or

All.

dit

lldtl are fastened beneath the tabla and or mally rest on cams formed onthe cam shaft f resting in bearings k on the bed plate. ein operatingcrank g is geared or otherwise suitably connected to the crank shaft.

The bed plate carries four columns to the upper ends of which fasten abrldge iece le adapted to carry the u per platen li 1n order to providefor the a justment of the up er platen, we mount the sameupon the brigepiece by means'of springs m, and interpose between the platen and tieunderside of the bridge plate, a wedge plate a which may be adjusted inposition by a nut o on a stud p secured to the bridge piece, or by othersuitable means.

In operation, the lower platen is slid along the table untilit is clearof the u per platen and the bridge piece, the card oard with coloredpaper, is laced thereon, and the punching and cuttin types are laced inposition on the card oard, suita le stops, guides or the like, beingprovlded on the platen if desired, for the purpose of positioning thework. The lower platen is then slid along the table into its positionfor the application of the pressure.

The wedge plate n is adjusted so that when the table b has been liftedby the cams 4 into its highest position, the plane surfaces of the twoplatens c and Z between which the work is pressed, are exactly parallel.1n order to afford a wide range of adjustment to suit differentthicknesses of work, the distance of the bridge piece from the bed platemay be varied by means of suitable nuts 5 secured on the columns z', asshown.

The upper platen having been adjusted to suit the thickness of the work,and the lower platen with the work thereon having been slid intoposition, the operating` lever g is turned until the cams have liftedthe table into its highest position. The cams A4 shown on the drawingare such that the operating lever would have to be moved at least 180degrees. A suitable stop may be fixed to the fra-me to determine theposition of the rest of the operating lever, if desired. The lever'having ap lied the pressure to the work, thetable rops, the work isremoved, and the shaft is then turned to its normal osition withouteffort. Alternatively, instea of turning the crank shaft towards andaway from a stop, it may be made to make a complete revolution.

It will be apparent that it will be easy for a skilled operator todetermine by one or two experimental operations what is the correctadjustment of the gap between the .two latens for the particular workand/or ies; the necessary adjustments being made to the wedge fn, bymeans of the screw o. When the machine has once been adjusted it remainscorrectly set for repetitions of the same or similar work.

It should be noted that the pivot for the table Z) on the base a and theshaft f are so arranged relative to each other that at the point ofmaximum lift of the cam the table b is always parallel to the upperplaten Z. After the cam. has passed its maximum lift position the tabledrops which enables the work to be removed and the shaft to be returnedto its inoperative position without eifort.

When a large number of cards or the like of the same kind are to beproduced, instead of placing the dies on the cardboard. as abovedescribed, they may be replaced by a die or dies fastened to the lowersurface of the u per platen. In this manner repetition wor is morequickly performed.

It will be readily appreciated by those skilled in the art that themachine forming the substance of our invention, and to which theforegoing description has been directed, possesses many advantages overother previously known machines for the same purpose. By correctlyadjusting the gap between the platens the. (proper pressure is appliedto the work provi ed the operating shaft is moved through its fulldistance as the cams must of necessity during this operation reach andpass the position of maximum lift. It is therefore not left to theoperator to guess when the correct pressure has been applied. Themachine also answers the various requirements above referred to. Thewearing parts are quickly accessible. On removing the lower platen andlifting the table by hand towards the upper platen or bridge piece, thecam shaft can be instantly removed from the machine. The pressure platescan then be quickly removed and replaced when necessary.

Many other modiications and changes in details will readily occur tothose skilled in the art without departing from the spirit and scope ofour invention as defined in the claims, but having now set forth theobjects and nature of our invention, and having shown and described astructure embodying the principles thereof, what we claim as new anduseful and desire to secure by Letters Patent is:
